ABUJA: At least 30 people have been killed after gunmen attacked travelers on a major highway in the southeastern part of Nigeria, rights group Amnesty International said.

The rights group said more than 20 vehicles and trucks were set ablaze during the Thursday attack along the Okigwe-Owerri highway in Imo state. Police confirmed the attack but not the death toll.

No group has claimed responsibility for the attack, but police suspect the Eastern Security Network, the paramilitary wing of the proscribed separatist group Indigenous People of Biafra.

The secessionist campaign in southeastern Nigeria dates back to when the short-lived Republic of Biafra fought and lost a civil war from 1967 to 1970 to become independent from the West African country. An estimated 1 million people died in the conflict, many from starvation.

The rights group said “international law requires the Nigerian government to promptly investigate unlawful killings with a view to bringing perpetrators to justice.”

One suspect connected to the attack was killed in a joint operation by law enforcement agencies, police spokesperson Okoye Henry said in a statement.

“An intensive manhunt is ongoing to apprehend the fleeing suspects and bring them to justice,” Henry said.

Two of the group’s prominent leaders, Nnamdi Kanu and Simon Ekpa, are in custody in Nigeria and Finland, respectively.

Kanu is standing trial on a seven-count charge bordering on terrorism and treasonable felony. He has pleaded not guilty to the charges.

The Nigerian government said Friday it has not begun extradition proceedings but is in talks with Finnish authorities to ensure Ekpa is held accountable for his alleged actions.

For many years Nigeria — Africa’s most populous nation with at least 210 million people — has been wracked by violence related to the activities of armed extremist groups.

KABUL: Taliban authorities have arrested 14 people in northern Afghanistan for playing musical instruments and singing, activities they restricted since taking power, provincial police said on Saturday.

The Taliban government has steadily imposed laws and regulations that reflect their austere vision of Islamic law since seizing power in 2021.

This includes cracking down on music in public, from live performances to playing at gatherings, in restaurants, in cars or on radio and TV.

The police said in a statement that on Thursday night in the capital of northern Takhar province “fourteen individuals... took advantage of the nighttime to gather in a residential house where they were playing musical instruments and singing songs, which caused disturbance to the public.”

Those detained were under investigation, it added.

After their takeover, Taliban authorities shuttered music schools and smashed or burned musical instruments and sound systems, saying music caused “moral corruption” and public disturbance.

Wedding halls are no longer allowed to play music, though segregated women’s sections often do so secretly.

Many Afghan musicians fled the Taliban takeover out of fear or in need of work after losing their livelihoods in one of the world’s poorest countries.

The Taliban authorities have encouraged former musicians to turn their talents to Islamic poetry and unaccompanied vocal chants — the only forms of music allowed under their previous rule from 1996-2001.
